Multiply numerators and denominators:
ac / bd
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
= 18 feet approx
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".
Answer:
-1 > x and x > 7.
Step-by-step explanation:
-12 < -3x - 15 < -36
What we are looking at here is a comparison with -12 being the smallest value, -3x - 15 being the second smallest value, and 36 being the largest value in the sequence. What you need to do is to make the problem into two separate problems:
-12 < -3x - 15
and
-3x - 15 < -36
Then we solve the equations like so (using PEMDAS):
-12 < -3x - 15
+15 +15
3 < -3x
/-3 /-3
-1 > x (the sign was changed the other way because when you divide by a negative it has to be flipped)
Now the other equation
-3x - 15 < -36
+15 +15
-3x < -21
/-3 /-3
x > 7
Now we have the inequalities of -1 > x and x > 7.
